Weight confusion.

[loveracing1988]

Because the suspension isn't rated for the weight. I'm not 100% sure but I believe the axles from 3/4 and 1 ton (SRW) are the same its all suspension that makes the difference.

The front axle is the same for all HD's. The rear axles are the same size for 2500 vs 3500 the difference is coil spring vs leaf springs.

Simple answer: Your max weight rating is controlled by the lowest capacity. As mentioned your axles are the same as on 3500s. On the 3rd Gen, the only difference between a 2500 and 3500 was 1 additional leaf spring.

I think you can still get the 2500s with the leaf springs actually, but probably not for long.

It could be funny if 3500s become cheaper than 2500s due to the simplicity of the rear suspension (since they are basically the same truck otherwise). Although that would only be due to the 2500s going UP in price, so maybe not so funny...

So, they go from coils to leaf springs, and BAM! It can tow 30k??

There has to be more to a 3500.
Either that, or they are de rating the 2500 so there is more of a gap between models.

I did specify the information I have is from 3rd Gen since that's what I own. New tricks have a lot more technical controls, the added leaf spring likely isn't the only difference.

I could be mistaken, but minus the new coil spring rears, I think most of the guts of the trucks were carryover from 3rd gen, frame, axles, etc. I put my 3rd gen flatbed on my 4th gen truck w/o any fitment issues. Also, it all pretty much looked the same laying underneath, not that my studies on the issue have been particularly scientific.

There is no 2500 with a Cummins that has a payload of 3140 pounds. My 2500 with the 6.4 isn't even that high and the engine in my truck is about 800 pounds lighter than the Cummins.

3140 is a max payload for a single cab cummins not a crew cab lol so the weight difference is apprx 420lbs between the motors..

And the 30k tow rating is for a tradesman cc drw 3500 with air suspension and a gooseneck..the rating is not for conventional towing

1 tons still have leaf springs but the payload difference between my 2500 and an equivalent 3500 is 400lbs of payload and like 1000lbs of towing

I was looking it up yesterday and all 2014 models of 3/4 tons made by the big 3 have roughly the same payload but the chevy and fords need the higher gear raitios (4.10 and 4.30 respectively) to be rated for the same towing a ram with 6.4 and 3.73 gear ratio those ratings are for regular cabs of course...real trucks dont need back seats

Towing and payload are 2 completely different things. The towing capacity between the 2500 and 3500 are almost identical untill you move up to the DRW same engine transmission ect. The way you get 30,000lbs towing is the single cab DRW 2wd with the HO 6.7 with the asian, the 3500 with out the asian (and SRW) has a almost identical towing capacity. There is only 10hp and 50tq difference between the two.

I also have to add gear ratio makes a huge difference. According to Rams web page the 6.4l 2500 can tow 50lbs less than the 3500 DRW with the 6.4 same axle. The 2500 only has the 3.42 rear axle. The 6.7 2500 3.42 is 300lbs less than the 3500 with the same ratio.. Witch mad as well be identical.

Pre 2014 the 2500 hemi trucks got the 10.5" rear axle vs the 11.5 for the Cummins trucks. Now all get the 11.5 except the drw gets a 11.8 now.

I think you can still get the 2500s with the leaf springs actually, but probably not for long.

It could be funny if 3500s become cheaper than 2500s due to the simplicity of the rear suspension (since they are basically the same truck otherwise). Although that would only be due to the 2500s going UP in price, so maybe not so funny...

No, there are no 2500's with leaf springs starting with the 2014 model year.

I could be mistaken, but minus the new coil spring rears, I think most of the guts of the trucks were carryover from 3rd gen, frame, axles, etc. I put my 3rd gen flatbed on my 4th gen truck w/o any fitment issues. Also, it all pretty much looked the same laying underneath, not that my studies on the issue have been particularly scientific.

In 2013 they redesigned the 3500 frame, in 2014 they carried that frame over to the 2500's. So if your 4th Gen was before those years that makes sense.

I retract what I said about the max payload of a 2500 with a Cummins. However, if you stay in the same line, my truck has a payload of 3100 pounds, the same truck with a Cummins is 2250, that is a 850 pound drop. Your truck with a 3600 pound payload drops to 2720 with a Cummins. All of those are for a 4x4 though. Your 2500 would have a payload of 4020 being a 2500, but the difference for the Cummins is from 2720 to 4250.
Bottom line is if you get a Cummins and want a 5th wheel or gooseneck step up to the 3500.

^^^ this guy has done his research

 

[regularcab2500]

Loveracing always does his research unfortunately i cant access rams towing guide on my phone lol...but i know my 2500 is only rated for 3600 just based on the gvwr being 10k and the truck weighing 6400 with me in it..

Regardless he is right about one thing for sure..if you have a gooseneck you should have a drw

And it also shows that a 6.4 option is the best if payload is what you require with some towing

I work midnights and get bored easily so I read that kind of stuff instead of doing something useful in the world. The main reason I had all of those figures is I had the brochure setting in front of me. Rams website is much to complicating to use to get multiple figures like that very fast.

It literally takes hours to sort through all the options on that thing haha but it is very useful..i wish ford and chevy would have something similar but then theyd probably get exposed lol

i played with the build tool back in summer and the price difference already wasn't that much. once i got all the options picked it was only something like $5000 more for the 3500 so really there wouldn't be much reason to pick the 2500 over the 3500

 

[regularcab2500]

Just wanted to put this out there because i found it interesting..

There seems to be some sort of discrepency and the numbers dont appear to make any sense whatsoever

The top picture is a 2015 the rest are 2014..how can the 2015 tow nearly 5000lbs more than the 2014 and have 400lbs more payload without any structural or component change? Also theres no way the ctd with 3.42 is rated for 17.5k towing but the 3.73 is only good for 13k!?! Dont add up..

I'm going to go out on a limb and say there web page is mixed up. That's the 5.7l towing capability. And if I'm not mistaken the cummins is only available with the 3.42 in the 2500.

That is correct.

 

[Kenny kustom]

I think there is a place for the 2500.
If I keep my current TT. It's a 2014. 30 ft. With a tongue weight of around 800.
Still leaves me room for gear.
It's just big enough to have given my 1/2 ton a workout.
I wouldn't see a reason to spend another 8k to go to a 3500.

For travel trailers they are fine. But for 5th wheels your options are limited because of how much payload you lose with the Cummins. I hope your just talking about negative equity for that 8k because like someone said above the price difference is only $500 or so.

 

[Kenny kustom]

Never bothered to look myself, but guy above said 5k.
Up here, that would be about 8k
